Well I'm in Europe, so I'm not sure if I can buy the same ones. It had novamin listed on the packaging ingredients so unless they're blatantly lying, it had it.

Heh, touché. The European one should have novamin. The effect isn’t supposed to be drastic. In fact I stopped using novamin as well because the studies I read didn’t show substantial difference vs fluoride toothpaste. I assume your dentist didn’t notice much? I’d still give nano hydroxyapatite a try.
